Tissue Sample Approval Checklist for Private Label Buyers

Approve a tissue sample against a written specification, an agreed evaluation method and a named sample reference. A pleasant first impression does not establish sheet count, packaging accuracy or repeat-order consistency. Use the record below to separate what you measured, what a supplier reported and what still needs confirmation before a purchase order.

BUYER CHECKLIST

Copy these fields into your sample approval record

Keep one record for each product and packaging version. Enter actual observations; leave unavailable results pending instead of filling them from a quotation.

Identity
Buyer SKU: ___; supplier sample reference: ___; received date: ___; production or reference sample: ___; related quotation version: ___. Photograph the pack and its identifying marks.
Construction
Declared fiber: ___; ply: ___; basis weight and whether it is per ply or total: ___; embossing: ___. Distinguish declared information from independently checked information.
Dimensions and quantity
Unfolded sheet width × length: ___; sheets or pulls per pack: ___; packs per carton: ___. For rolls, also record width, length or count, outer diameter and core dimensions.
Method and result
Property checked: ___; method: ___; sample condition: ___; number of units examined: ___; individual readings: ___; agreed acceptance range: ___. Keep subjective feel separate from instrument readings.
Packaging
Dieline version: ___; artwork version: ___; barcode verification record: ___; pack fit: ___; carton dimensions: ___. A plain reference pack does not approve final printed packaging.
Decision
Approved / conditional / rejected: ___; open conditions: ___; responsible person: ___; resolution date: ___; retained sample location: ___. Link approval to the exact specification version.

Choose the evidence that answers the question

Softness or surface feel
Use a documented comparison with the buyer's chosen reference and the same handling conditions. Record who assessed it and what they noticed; do not convert a preference into an invented laboratory score.
Strength when wet
Ask the laboratory which method and units it will use. ISO 12625-5:2024 describes wet tensile strength measurement. An informal wet handling check can flag concerns but is not an equivalent certified test.
Absorption
Specify whether the question concerns absorption time, capacity or a real service task. ISO 12625-8 describes a basket-immersion method. Keep method-based results separate from kitchen or washroom trials.
Repeat production
Agree tolerances, inspection scope and how a changed material or pack is approved. A retained sample gives a comparison reference; it does not prove every future batch will match.

Dry versus wet tensile strength: compare the conditions

Tensile strength concerns the force a test piece withstands before breaking, reported on the method's stated basis. It is a different property from softness or absorption. These are method-selection notes, not VELUPLY test results.

Dry-condition question
Ask the laboratory to identify its conditioning, specimen direction, dimensions and reporting units. ISO 12625-4:2022 describes tensile measurement for tissue products. Keep the result linked to the sample and method; a hand-pull demonstration is not a comparable laboratory measurement.
Wet-condition question
ISO 12625-5:2024 concerns tensile measurement after wetting. Ask for the wetting procedure, specimen direction and units as well as the value. Do not compare an uncontrolled soaked sample with a conditioned dry sample and call the difference a standardized result.
Comparing results
Record dry method/result: ___; wet method/result: ___; units: ___; direction: ___; sample identity: ___. Compare only compatible reporting bases. A stronger dry result does not by itself establish stronger wet performance, and neither result alone selects the right product for every use.

Lint observation worksheet for an agreed buyer trial

This is a repeatable observation protocol to agree with the buyer, not a standardized laboratory lint test. It provides no universal pass threshold. For a formal lint claim, commission an appropriate method and report from a competent testing provider.

Define the comparison
Sample IDs: ___; intended task: ___; reference sample: ___; trial surface and cleaning method: ___; storage/conditioning period: ___; sheets examined per sample: ___. Use the same defined surface and handling conditions for both samples.
Fix the handling
Write the operation before starting: contact area ___; number of strokes or pulls ___; direction ___; pressure-control approach ___; operator ___. Do not invent a numeric laboratory force from hand pressure. Record that limitation if the task is manual.
Observe consistently
Photograph the clean surface first, then each trial result with the same lighting, distance and background. Record visible loose fibers, particles and sheet damage separately: ___. Clean the surface between samples and keep original photographs.
Decide and retain
Buyer-agreed visual acceptance rule: ___; observations by sample: ___; decision and exceptions: ___; reviewer: ___. If pressure or handling could explain the difference, repeat the agreed trial or request formal testing. Do not publish a laboratory-style lint score from this worksheet.

DECISION POINTS

What to align before the next commitment.

01

Worked example: a conditional decision

Illustrative only: a buyer receives a two-ply facial tissue reference with an agreed sheet size, but the proposed printed box is absent. The buyer may record the paper evaluation as acceptable while leaving packaging approval open. That decision must not be copied into a purchase order as unconditional approval of the finished retail SKU.

02

Keep the comparison fair

Compare samples under consistent handling and storage conditions. If one sample was compressed, damp or unpacked for longer, record that difference before attributing the result to material quality. Ask the testing provider to define conditioning when commissioning formal measurements.

03

Separate a reference from a commitment

A showroom sample can help choose a direction. Before ordering, ask which features it represents and which will change. The production specification, approved artwork and commercial terms should identify those differences rather than relying on a verbal promise that the order will be similar.

WORKING SEQUENCE

A clearer route from question to decision.

  1. 01

    Define the intended use and the acceptance questions before requesting samples. Choose the properties that matter for that use instead of collecting an unstructured list of impressions.

  2. 02

    Assign a reference to each received sample and record its condition. Check identity, dimensions and quantity before comparing performance or price.

  3. 03

    Run the agreed buyer checks or commission a matched test. Record exceptions, methods and raw observations, including a pending status when no result exists.

  4. 04

    Resolve conditions in writing, retain the agreed reference and attach the final approval record to the order. Reopen approval when a material, dimension, artwork or pack version changes.

DIRECT ANSWERS

Questions buyers ask before moving forward.

01How many samples should I inspect?+

There is no universal sample count for every tissue order. Agree the inspection approach with the supplier or inspection provider according to lot size, risks and the properties being checked. Record the scope so a small reference check is not presented as a statistical acceptance of the entire shipment.

02Does a certificate replace sample approval?+

No. A certificate and a physical sample answer different questions. Match any certificate or report to its holder, product scope and quoted route, then separately approve the sample's relevant specification and packaging.

03Can I approve paper now and packaging later?+

Yes, as a clearly conditional record. Name the approved paper reference, list the unresolved packaging fields and specify who must release them. Do not treat the complete retail product as approved until the conditions are closed.

SOURCES & LIMITS

Trace the question and the verification.

This is a buyer planning checklist, not a laboratory report or a VELUPLY product approval. The ISO references identify published test methods; they do not establish that a sample has been tested or passed. Confirm the applicable method and edition with the testing provider.
